Please find attached my HCL report for my T480s 40GB RAM.
Furthermore I noticed an error in the HCL.
A T490s is listed as a T470s I noticed because it mentioned a i7 Whiskey lake
CPU and a T490s type # 20nx000gmz (this is a T490s)
I will need to dig in to QUBES OS soon.
Have a great day!

Thank you Amadeus for your HCL report, which is [online](Hardware compatibility list (HCL) | Qubes OS) now.
In addition I removed the erroneous HCL entry referring to the ThinkPad model 20nx000gmz as T470s as you suggested. The respective reporter had resubmitted the report at a later time correctly calling out the machine as T490s.
Funny enough, your own model number 20L8SA2V00 cannot be found by Google at all except for your very post to this list.

So Whiskey Lake helps you to reach the Ballmer Peak (xkcd: Ballmer Peak)? (Sorry, I couldn't resist ;-))
